Could not compile hamachi-v0.14 on Alpha-2.2.[36]

[Bernhard Kaindl]

I all,

   I´ve just got an error when compiling hamachi-v0.4 on an Alpha System.
It compiled against 2.0.36, but using 2.0.x for the hamachi is not reasonable
for us because our upcoming AXP release of SuSE Linux 6.1 will be equipped
with system tools for 2.2.x-Kernels.

This is the driver i tried to compile against 2.2.3 and 2.2.6:

http://www.nscl.msu.edu/~kasten/perf/hamachi/src/hamachi-0.14.tar.gz

Compile commands were:

gcc -DMODULE -V2.7.2.3 -D__KERNEL__ -Wall -Wstrict-prototypes -I/usr/src/linux/net/inet -O6 -o hamachi.o -c hamachi.c
and
gcc -DMODULE -D__KERNEL__ -Wall -Wstrict-prototypes -I/usr/src/linux/net/inet -O6 -o hamachi.o -c hamachi.c
(the latter uses egcs on our system)

These are the error messages:

make: *** [hamachi] Error 1

I see that this should be the error line:

/usr/include/asm/current.h:4: global register variable follows a function definition

Problabyl I could fix this myself, but I wanted to report this anyway,
and probably somebody reading this says: "Clear, do this and this...."

I also would like to know, if there is some driver update needed to make
it work with 2.2.6-AXP or if it should only take some small changes to 
make it compile(and work?).

with best regards,
